Any little boy loves to putter with tools and guns and any man who shoots remains a little boy forever in this respect. Here is a book that will keep them quiet for hours in the workshop, Mr. Howe arranges for them. He gives suggestions for the work bench, tools they'll need, starts them on various lines of investigation, turns on their imagination so they are all set to go ahead inventing new gadgets and refining others. There's plenty of valuable information but he never takes away the fun of letting them become guncraftsmen themselves. For camps, for schools, for workshops, for boys from 8 to 80.
